I made some prints and sandwiched them between dry newsprint topped with heavy books to flatten them. But, I think I left them too long or a least too wet because some of them got moldy. A setback to say the least. I let the next batch dry in the open air which didn’t leave them very wrinkled anyway. Some solutions to mold growth that I learned about on the Internet include addind a few drops of bleach or Dettol to your spray bottle. I’m not sure how this would effect the pigments, but I will experiment and see what happens.
